Just spent too much time tracking down a bug, in debug resistant code, left me equally satisfied and disappointed...

Yeah that happens, I was a couple months ago head hunted and persuaded to submit to a corporate sponsored community event, they even wanted a specific session of mine. Suggested a few dates I was available, then silence.

Only happened twice so far for me. Mostly get rejected, that’s fine, I’m on a couple of content committees, and competition is fierce. Some have raised the bar, req more effort for submitting speakers: tailored video per session, links to previous talks. IMHO, a rejected email, not too much to ask.

Man, some conferences are notoriously bad at notifying CFP rejections, they're often really good at signing you up for mailing lists. As soon as you have a speaker selection, please notify. But it's worse when you set the agenda before notifying accepted speakers. Happened to me and had 📅conflict.

Valid feedback to @frame.work , Pluton would be preferred, yes. It has USB front header ports on the motherboard, so it should be able lead somewhere.

They've got native TPM 2.0 support, front ports are modular, same as Laptops, so you pick which you want.

The sign tool works great already with Azure Trusted Signing, it's getting certs into NuGet org gallery for your org that currently is painful. By design public keys need to be registered or push will fail. Which isn't a big issue for long lived certs, but short lived causes chicken egg for CI.
